Abstract: Ordos Basin is rich in tight gas resources, after 20 years of development practices and technical innovations, it has become China’s largest natural gas production base. The gas reservoir development process is divided into 3 stages of evaluation, production establishment, stable production and recovery enhancement. During the evaluation stage, a continental tight gas depositional model and development theory were established, as well as key technologies such as low-cost development strategies, preferential selection of enrichment zones, and evaluation of development indicators, which promoted effective reserve utilization. In the production establishment stage, the increasing geological understandings and the demand for improving single-well output led to the development of well type and well pattern optimization and reservoir fracturing stimulation techniques, supporting a rapid increase in production. In the stable production and recovery enhancement stage, precise reservoir characterization continued to be improved, forming a series of recovery enhancement technologies with a focus on improving reserve utilization. Supported by a large-platform, factory-like operation mode, these technologies can reduce costs and increase efficiency, thus ensuring the benifit and effectiveness of gas field development. The recommendations include tackling problems in key technologies, such as continuously implementing fine potental tapping, three-dimensional development of Upper and Lower Paleozoic tight zones, as well as efficient utilization in water-rich areas, and improving comprehensive treatment measures for low-production and inefficient wells. These efforts aim to continuously enhance development levels and benefits.
